This investigation assessed the relationship between traumatic stress
exposure and dissociation in male Vietnam theater veterans from three
ethnic groups. Subjects were African-American (N = 61), Caucasian (N =
91), and Hispanic (N = 73) veterans who completed the Dissociative Ex
periences Scale and a measure of war zone stress exposure, and who wer
e rated on the Peritraumatic Dissociative. Experiences Questionnaire-R
ater Version. Greater exposure to war zone stress was associated with
reports of more dissociation at the time of trauma and with more gener
al dissociative experiences both when the data were pooled and when ex
amined separately for each group. After controlling for the effects of
war zone stress exposure, the significant differences found in peritr
aumatic and general dissociative experiences across the three ethnic g
roups no longer were evident. This investigation demonstrated that amo
ng American Vietnam veterans, greater exposure to traumatic stress is
related to more dissociative experiences, regardless of ethnicity.
